The IA-DUET study aimed to compare azole-echinocandin combination with azole monotherapy for invasive aspergillosis. Recruitment was hindered by patient ineligibility, competing studies, and guidelines favoring combination therapy when azole resistance was unknown. The low IA-attributable mortality suggests future trials may benefit from cluster randomization or composite endpoints to enhance efficiency.
